#CVE-2020-15663: Downgrade attack on the Mozilla Maintenance Service could
have resulted in escalation of privilege
Reporter
Xiaoyin Liu
Impact
high
Description
If Firefox is installed to a user-writable directory, the Mozilla
Maintenance Service would execute updater.exe from the install location
with system privileges. Although the Mozilla Maintenance Service does
ensure that updater.exe is signed by Mozilla, the version could have been
rolled back to a previous version which would have allowed exploitation of
an older bug and arbitrary code execution with System Privileges.
Note: This issue only affected Windows operating systems. Other operating
systems are unaffected.

#CVE-2020-15664: Attacker-induced prompt for extension installation
Reporter
Kaizer Soze
Impact
high
Description
By holding a reference to the eval() function from an about:blank window,
a malicious webpage could have gained access to the InstallTrigger object
which would allow them to prompt the user to install an extension.
Combined with user confusion, this could result in an unintended or
malicious extension being installed.

#CVE-2020-15670: Memory safety bugs fixed in Firefox 80 and Firefox ESR
78.2
Reporter
Mozilla developers and community
Impact
high
Description
Mozilla developers Jason Kratzer, Christian Holler, Byron Campen, Tyson
Smith reported memory safety bugs present in Firefox 79 and Firefox ESR
78.1. Some of these bugs showed evidence of memory corruption and we
presume that with enough effort some of these could have been exploited to
run arbitrary code.
